Summary

Story summary

Cosmologists theorize that the universe underwent rapid expansion, known as inflation, during the Big Bang.
Evidence for inflation is found in the cosmic microwave background and gravitational waves, which are challenging to detect.
The Laser Interferometer Space Antenna (LISA), set to launch in the mid-2030s, aims to detect these primordial gravitational waves.
The success of LISA is uncertain, and plans for its proposed successor, the Big Bang Observer, are not yet established.
